TOOL-HANDLE.

Specification of Letters Patent.

Application filed April 21, 1910.

Patented Aug. 30, 1910. Serial No. 556,677.

To all whom it may concern:

Be it known that I, JOHN D. THOMPSON, a subject of the King of Great Britain, residing at Toronto, county of York, Province of Ontario, Canada, have invented a certain new and useful Improvement in Tool-Handles, and declare the following to be a full, clear, and exact description of the same, such as will enable Others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to tool handles.

It has for its special object a handle adapted to be used with engraving tools.

In the drawings :-F igure 1, is a side elevation of the handle, and a line graver held therein. Fig. 2, is a reverse plan view of the tool-holding part of the handle. Fig. 3, is a side elevation of the several parts. Fig. 4c, is a side elevation of the handle with the burnishing tool held therein. Fig. 5, is a reverse plan view of the tool with the burnisher held therein. Fig. 6, is a side elevation of the burnisher. Fig. 7 is an end elevation of the handle head.

The handle consists of the holding part 1 of wood or similar material, in which there is inserted a shank 2 which terminates at its front end with an engaging member 3 serrated on that side-which is normally held downward and provided on the side opposite the serrations with a screw abutting face 4; a projection 5 extends therefrom that is adapted to engage in the socket 6 of the tool. On the member 3 is pivotally supported a clamp comprising a split ring 6, the lips 7 of which along the slot extend under the serrations 8 of the member 3. The projection or nose 5 extends beyond the clamp 6 and the clamp is capable of aslight oscillating motion on its pivot 9. The tool is provided with flanges 10 that project from a web; the web enga es in the slot between the lips 7 and the anges engage between the lips and the serrated face. The tool may be provided with serrations 11 to engage in the serrations 8, or it may be left plain and provided with a socket 6 within which the nose 5 engages. Across the clamp underneath the serrations 8 in the assembled tool a pin 12 crosses from side to side of the clamp and the ends are riveted over, making the pin a permanent fixture with respect to the clamp; this pin is spaced from the lower surface of the member 3 to permit the insertion under the pin and between the pin and the face of a tail prong 13 on some of the tools. A tool G, which is a line graver, may be inserted in the handle with either end foremost. As shown in Fig. 1, it is properly inserted for draw-line engraving; inserted with the inclined end foremost it is properly located for sharpening purposes or for push-line engraving, although a push-line engraver is not commonly used. The tool B is inserted with the tail 13 under the pin or rivet 12, and with the nose 5 of the member3 engaging in the socket 6 and the clamp is then drawn tightly against the flanges 11 of the tool B by means of a thumb screw 14, and the tool is very firmly and securely held in place.

What I claim is 1. A handle for gravers tools, having'in combination a tang terminated at its front end with a member provided with a serrated face, and with a smooth bearing face opposite the serrated face, a split clamp pivotally connected to said tang and provided with overhanging lips extending under said serrated face, a thumb screw engaging through a wall of the clamp against the engaging portion of the tang, substantially as described.

2. In a handle for gravers tools, having in combination a tang, a serrated projection extending from the tang, a nose terminating the serrated portion, a split clamp pivotally connected to the tang provided with overhanging engaging lips and with a thumb screw and a pin engaging across the split clamp, substantially as described.

3. A handle for gravers tools, having in combination a tang terminated at its front end with a member provided with a toolengaging face and with a bearing face opposite the tool-engaging face, a split clamp pivotally connected to said tang provided with edges extending along the slit and which overhang the tool-engaging face, a thumb screw engaging through a wall of said split clamp and against the bearing face opposite the tool-engaging face, substantially as described.

4. In a handle for gravers tools, a combination of a tang, a projection extending from the tang and provided with a nose attached to engage a socket in the tool, a split clamp pivotally connected to the tang provided with edges extending along the split which overhang the tool-engaging face of the projection, a pin engaging across the split clamp at the rear of the split portion thereof, substantially as described.

5. A handle for gravers tools, having in combination a tang terminated at its front with a member provided with a tool-engag ing face a bearing face opposite the toolengaging face a split clamp terminal connected to said tang and provided with edges which overhang the tool-engaging face of said tang, a thumb screw engaging through a wall of the clamp against the bearing portion of the tang, substantially as described.

In testimony whereof, I sign this specification in the presence of two Witnesses.
